The home side seemed set to register just their second win in six games in all competitions when the returning Edinson Cavani put them in front after six minutes.

But Aronica, who had only been on the field five minutes after coming on as coach Walter Mazzarri sought to shore up defensively and cling on to their one-goal advantage, attempted a back pass which was intercepted by Gianluca Sansone. He then displayed commendable calm to round home keeper Morgan De Sanctis and slot into an empty net.

It was hard on Napoli who had the majority of chances in an open game.

Alejandro Gomez was in inspired form as Catania pulled off a remarkable 4-0 thumping of Lazio.

Gomez opened the scoring as early as the eighth minute to set Rolando Maran's men on their way before Francesco Lodi netted from the spot midway through the first-half.

Catania were out of sight after 28 minutes when Gomez netted from close range and the Argentinian teed up Pablo Barrientos to seal the rout after the interval.

The victory was Catania's fourth victory from six matches at the Stadio Angelo Massimino while Lazio's wretched run continues. Having been among the early leaders, Lazio's Serie A title challenge had been undermined by three games without a win but the result in Sicily must heavily damage morale within the camp.

Ivo Pulga was given a reminder of the harsh realities of life in Serie A as his successful start to life in charge of Cagliari was halted 4-1 by in-form Fiorentina.

Pulga is an icon in Sardinia as a result of his playing days, and has done little to change that since taking the managerial reins from Massimo Ficcadenti last month, winning all four of his games in charge.

But La Viola put a stop to that in resounding fashion, with goals from Gonzalo, Stevan Jovetic, Luca Toni and Juan Cuadrado putting them into fourth place. Federico Casarini had equalised for Cagliari who left the Stadio Artemio Franchi with their bubble well and truly burst.

AS Roma reacted to recent criticism after suffering back-to-back defeats with a clinical 4-1 win over Parma at the Stadio Olimpico.

Francesco Totti put the Giallorossi ahead in the 11th minute and further goals from Pablo Osvaldo, Erik Lamela and Mattia Destro sealed a comfortable three points.

Josip Ilicic grabbed a consolation after Destro was sent off, but the win was never in any doubt and could have been even greater as Roma continued to push forward.

Second-half goals from Italy internationals Alessandro Diamanti and Antonio Di Natale cancelled each other out as Bologna and Udinese drew 1-1 at the Stadio Renato Dall'Ara.

Diamanti tapped home from close range immediately after half-time for the home side but Di Natale responded in the 73rd minute to earn Udinese a point.

The result makes little difference to either side's standing in Serie A, with Bologna remaining in the bottom three and their visitors in mid-table.

Sampdoria lost their sixth game in a row to increase the pressure on coach Ciro Ferrara with a 2-1 reverse at home to Atalanta.

Giacomo Bonaventura gave the visitors the lead in the second minute, but Enzo Maresca levelled for the Blucerchiati early in the second half.

Giuseppe De Luca put the Bergamese side in front again in the 76th minute and they withstood a late rally from Samp to take all three points at the Stadio Luigi Ferraris.

Luigi Del Neri remains winless since taking charge of Genoa as struggling Siena inflicted a fourth straight defeat on the Rossoblu with a 1-0 victory at the Stadio Artemio Franchi.

Massimo Paci's goal early in the second half gained the Tuscan side only their second win of the season, the first coming against Bologna at the end of September, and lifted them to within three points of their opponents, who occupy the first position above the relegation zone.

It was also a personal satisfaction for Siena coach Serse Cosmi, who led Genoa to the Serie B title in 2005, but left following their imposed relegation to Serie C due to financial malpractice.

Pescara picked up their first victory in over a month as Elvis Abbruscato's first goal of the season and a late strike from Vladimir Weiss earned a 2-0 win over Parma.

It was only Pescara's second victory in front of their own fans this season, coming much to the relief of their under-fire coach Giovanni Stroppa, with both goals arriving in the second half.

Abbruscato then scored his first goal of the season in the 49th minute when he held off the challenge of Gabriele Paletta before picking his spot in the far corner. Weiss sealed the victory deep into stoppage time with a fine individual effort, using pace and strength to carry the ball 30 yards before dispatching it in off the inside of the right-hand post.
